If a wavelength of a wave increases, but the wave speed remained the same, would the frequency increase, decrease or stay the same?

When we are provided either a) two angles and one side or b) two sides and an excluded angle, we utilize the sine rule. When we have either a) three sides or b) two sides and the included angle, the cosine rule is used.

Therefore, you either need two sides and an angle to solve for the remaining side or all three sides to solve for an angle. Therefore, you can't just use the rule of cosines if you have two angles (which allows you to figure out the third, making it technically three angles) and a side. The Law of Sines cannot be applied to triangles with two sides and an included angle or three sides.

Answer:

When you push on the door and it opens, the action-reaction forces at play are the force you exert on the door and the force the door exerts on you.

According to Newton's third law of motion, when two objects interact, they exert equal and opposite forces on each other. In this case, when you push on the door, you are applying force to the door. This force is then met by an equal and opposite force from the door, which pushes back against your hand.

The magnitude and direction of the forces depend on the relative mass and acceleration of the objects. In this case, the door is much heavier than your hand, so it requires a greater force to move it. As a result, the door exerts a greater force on your hand in the opposite direction, causing your hand to move backward.

Overall, the action-reaction forces at play in this situation are the force you exert on the door and the force the door exerts on you, which are equal in magnitude but opposite in direction. These forces act to accelerate the door and your hand in opposite directions, causing the door to open and your hand to move backward.

The presence of friction in our experimental setup results in a ratio of (total moment before/total momentum after) the collision to be less than 1.0 because kinetic energy is lost to friction.

Collision is a case where one moving object or person violently collides with another.

Friction causes a constant loss of energy in moving objects because work is done by friction.

As we know momentum is P = m*v i.e. momentum (P) is directly proportional to the mass and velocity.

Due to presence of friction, velocity will be reduced after collision and hence the total momentum after collision will be reduced.

So,

Total momentum before collision < Total momentum after collision

Therefore, the ratio of total momentum before and after collision will be less than 1.0.

The combustion of methane can be calculated using the data from the bomb calorimeter and the amount of water in it.

First, determine the heat of the combustion of methane. This can be done by taking the heat capacity of the calorimeter, subtracting the heat capacity of the water, and then multiplying the resulting number by the mass of methane used.

For example, if the heat capacity of the calorimeter is 5 kcal/°C and the heat capacity of the water is 1 kcal/°C, and the mass of methane used is 2 g, the heat of combustion of methane would be (5 - 1) x 2 = 8 kcal.

Next, calculate the change in temperature of the water. This can be done by taking the heat of the combustion of methane and dividing it by the heat capacity of the water.

For the example above, the change in temperature of the water would be 8 kcal/1 kcal/°C = 8°C.

Finally, calculate the combustion of methane. This can be done by taking the heat of the combustion of methane and dividing it by the change in temperature of the water.

The constant acceleration of the green car which passes red color car is  2.81 m/s^2.

In this problem, the initial positions of the red and green cars are xr = 0 and xg = 220 m, respectively, and their initial velocities are vr = 20 km/h and vg = 0. When the red car has a velocity of 20 km/h, the cars pass each other at x = 44.5 m, and when the red car has a velocity of 40 km/h, they pass each other at x = 76.6 m.

We can use these two equations to solve for the acceleration of the green car. First, we convert the velocities from kilometers per hour to meters per second by dividing by 3.6. This gives us vr = 5.56 m/s and vg = 0 m/s.

Then, we can substitute these values into the equation for position and solve for the acceleration. When the red car has a velocity of 20 km/h, the equation becomes:

x = 0 + 5.56t + 1/2at^2

x = 44.5

Solving for a, we find that the acceleration of the green car is a = 2.61 m/s^2.

When the red car has a velocity of 40 km/h, the equation becomes:

x = 220 + 11.11t + 1/2at^2

x = 76.6

Solving for a, we find that the acceleration of the green car is a = 2.61 m/s^2.

When the red car has a velocity of 40 km/h, the equation becomes:

x = 220 + 11.11t + 1/2at^2

x = 76.6

Solving for a, we find that the acceleration of the green car is a = 3.02 m/s^2.

Since the acceleration is the same in both cases, we can take the average of these two values to find the constant acceleration of the green car. The average of 2.61 m/s^2 and 3.02 m/s^2 is 2.81 m/s^2.

The time required for each new whole cycle to be generated is 0.25 s. So answer e is correct.

Sinusoidal water waves are a type of wave that is generated in a large ripple tank. These waves travel at a rate of 20cm/s and their adjacent crests are 5 cm apart. The time required for each new whole cycle to be generated is dependent upon the velocity of the wave and the distance between the adjacent crests.

To calculate the time required for a new whole cycle to be generated, we must first determine the wavelength of the wave. The wavelength is equal to the distance between the adjacent crests, which is 5 cm. Now that we know the wavelength, we can use the formula

v=λ/t

where v is the velocity of the wave (20 cm/s), λ is the wavelength (5 cm), and t is the time required for one cycle to be generated.

By substituting the given values into the equation, we can calculate the time required for one cycle to be generated.

t=λ/v,

so t=5 cm/20 cm/s,

The period of oscillation of the sphere is 161 seconds.

What is oscillation?

Oscillation is the repetitive movement of a particle or system about a central position or equilibrium point. Oscillations can occur in a variety of forms, such as periodic oscillations (which repeat at regular intervals), damped oscillations (which gradually decrease in amplitude over time), and driven oscillations (which are driven by an external force).

To find the period of oscillation of the sphere, you need to know its angular frequency, which is given by the following formula:

angular frequency = sqrt(k / I)

where k is the angular spring constant (also known as the torsional spring constant), and I is the moment of inertia of the sphere.

The angular spring constant is given by the following formula:

k = torque / angle of twist

Plugging in the values from the problem, you get:

k = 0.20Nm / 0.85rad = 0.235Nm/rad

The moment of inertia of a solid sphere is given by the following formula:

I = (2/5) * mass * radius^2

Plugging in the values from the problem, you get:

I = (2/5) * 95kg * (15cm)^2 = 6750kg*cm^2

Plugging these values into the formula for angular frequency, you get:

angular frequency = sqrt(0.235Nm/rad / 6750kg*cm^2) = 0.0062rad/s

The period of oscillation is the reciprocal of the angular frequency, so you can calculate it using the following formula:

period = 1 / angular frequency

Plugging in the value for angular frequency that you calculated above, you get:

period = 1 / 0.0062rad/s = 161s

Therefore, the period of oscillation is 161 seconds.

The ride is powered by a motor that makes the swing ride spin around the centre axis of the ride. The chairs move in a circle at a moderate speed. The forces acting on a swing rider are the tension in the chain and the weight of the rider.

When the swing moves from the lowest point up to either peak, the main force acting is momentum; and when the swing falls from either peak to its lowest point, the main force acting is gravity. The movement of the pendulum is said to be simple harmonic motion because the restoring force acts directly proportional to the displacement and is directed towards the equilibrium position. Hence, the movement of the Pendulum is simple harmonic motion.

Kirchhoff's voltage law states that the algebraic sum of the potential differences in any loop must be equal to zero as: ΣV = 0.

Given the various resistances and circuit we will apply Kirchhoff's voltage  law and Junction Law

Apply Kirchhoff's law to the left side loop to get;

Applying the law of Junction to get;

I₁ = I₂ + I₃

Put I₂ + I₃ for I₁ in eq 1 to get;

21 = 30.5(I₂ + I₃) + 6.25 I₃

21 = 30.5I₂ + 30.5I₃ + 6.25 I₃

Thus;

I₁ = -0.5459 + 1.02445

I₁ = 0.47855

Hence we can conclude that the currents flowing in the circuit are as follows : I₁ = 0.47855 A,  I₂ = -0.428 A,  I₃ = 1.02445 A
